OSM will honor any previously established contracts with Dr McLellan.

We have 4 locations throughout Dane County: West Madison, North Madison, Verona and Windsor.  Please check out our website for hours & directions.

Future appointments that were originally scheduled in Middleton should be rescheduled at any of the four OSM locations depending on your preference.

Call us at  608-664-9500.  Since every patient is an individual and has different retention requirements, our receptionists can not quote a fee over the phone.  You will likely need an appointment to assess your specific retainer needs.

Call us at 608-664-9500 to schedule a repair.   In the meantime please see for a list of remedies.

Our goal, during this transition, will be to provide efficient treatment care.  We will strive to keep any delays to a minimum.   Dr. McLellan will communicate any special considerations to facilitate completion of your orthodontic treatment.

Technology  is an important part of diagnosis and treatment in our practice too.  Please see our website for more information
